Since the dawn of humanity, people have been discovering and inventing new methods to communicate. From smoke clouds to cloud storage, the evolution of communication technology has been beyond the wildest imaginations of our ancestors. The team at Ooma is proud to present this ultimate timeline of communication technology, tracing back all the way to the origin of speech. You will discover the origin of the telephone, when computers were invented, the first email sent and so much more! Without further ado, let’s dial in.

When was the telephone invented?

The first practical telephone was patented in 1876, but the true origins of the telephone are a bit shrouded in controversy. Scottish-born Canadian-American inventor Alexander Graham Bell is credited with being the inventor of the telephone. However, the idea and design do not wholly belong to him.

So, who was the true inventor of the telephone? While Alexander Graham Bell is described as the “father of the telephone,” it was actually an Italian immigrant named Antonio Meucci who first developed the concept and design for a talking telegraph (or telephone) in 1849. Just four years before Bell patented his telephone design, in 1871, Meucci filed a caveat (or an announcement of an invention) for his design of a talking telegraph. Unfortunately, Meucci could not afford to renew the patent on his design, so his role in the invention of the telephone is often overlooked. Worry not, there was some justice! On June 11, 2002, the United States House of Representatives passed a resolution honoring Meucci’s contributions.

The story of who invented the telephone gets even more murky. American electrical engineer Elisha Gray filed a patent for his telephone design on February 14, 1876, the same day that Bell’s lawyers filed his patent. No one truly knows what occurred between Bell’s lawyers and the patent officers on that day, but the patent was ultimately awarded to Bell. Over the following weeks, Bell improved upon his version of the telephone with features that were remarkably similar to those illustrated in Gray’s preliminary patent application. However, Ellis Spear, a senior official at the patent office, denied any interference between Gray and Bell’s applications. This situation calls to mind the Sivowitch Law of Firsts, which dictates that “whenever you prove who was first, the harder you look you will find someone else who was more first.”

The first phone call ever made was on March 10, 1876, just three days following the publication of Bell’s telephone patent. Alexander Graham Bell made history when he successful conveyed this message to his assistant Thomas Watson: “Mr. Watson, come here — I want to see you.” While the words were crackly and indistinct, they were the first to be spoken over the telephone.

So did Bell really invent the telephone? That is up to you to decide. Either way, phones have become an integral part of how we live, work and play!

When was the mobile phone invented?

On April 3, 1973, Motorola researcher and executive Martin Cooper made the first mobile phone call to his rival Dr. Joel S. Engel of Bell Labs. Standing on a Sixth Avenue sidewalk in Manhattan, he called Engel via a device the size of a brick and said: “I’m calling you on a cell phone, but a real cell phone, a personal, handheld, portable cell phone.” So, does this answer the question, “What was the first mobile phone?” Unfortunately, government regulation and manufacturing issues slowed the progress of bringing the phone to market. It took a decade for a version of that Motorola DynaTAC (Dynamic Adaptive Total Area Coverage) phone to become commercially available. And how much did the first cell phone cost? At the time, the Motorola DynaTAC cost a staggering $3,995! In today’s economy, that equates to around $12,600.

When was the internet invented?

January 1, 1983 is widely considered to be the official birthday of the internet. Prior to this world-transforming day, there was no standardized way for computers to communicate with each other. A new electronic communications standard called the Transmission Control Protocol/Internet Protocol (TCP/IP) provided a universal language for computers, enabling them to communicate with each other. ARPANET (the predecessor of the internet) and the Defense Data Network officially switched over to the TCP/IP standard on January 1, 1983, marking it as the official birth of the internet.

Who invented the TCP/IP model?

The Transmission Control Protocol/Internet Protocol was developed by Robert E. Kahn and Vinton G. Cerf, computer scientists working for Defense Advanced Research Projects Agency. They developed an internet architecture that allowed various networks (and their connected devices) to exchange data packets in a shared, standardized language. In 2004, Kahn and Cerf received the Turing Award for their work as internet pioneers. Without this foundational work, our home phone, business phone and business internet services would not exist!

We mentioned ARPANET being the predecessor of the internet before, but what is ARPANET exactly? ARPANET stands for the Advanced Research Projects Agency Network. It was a revolutionary computer networking project operated by the United States Department of Defense and ultimately paved the way for the internet we know today. Initially, ARPANET was designed to allow communication and information sharing between government agencies and research institutions. ARPANET introduced packet-switching technology, which allowed data to be broken down into smaller packets that could be exchanged across a decentralized network.

Time and Event

Description

100,000 BCE

Origin of speech

While not a technology, the origin of human speech sparked the development of communication technology. Early imperfection of speech allowed for the natural rise of new forms of communication, such as symbols.

30,000 BCE

Origin of symbols: Cave paintings

The earliest known use of symbols for communication were cave paintings. These grew in complexity over time. Animals were a popular subject.

10,000 BCE

Petroglyphs

It took humans about 20,000 years to advance from cave paintings to petroglyphs, or carvings into surfaces.

9,000 BCE

Pictograms > Ideograms

Humans began using pictograms. Tokens marked with simple pictures were used to label farm produce. These became more abstract over time, evolving into ideograms.

3,500 BCE

Early scripts/cuneiform

Ideograms evolved into the first logo-syllabic writing system known as cuneiform.

3,100 BCE

Hieroglyphs

Egyptians created hieroglyphs, a formal writing system that combined logographic, syllabic and alphabetic elements.

16th century BCE

Phoenicians develop the alphabet’s ancestor

Over time, people began simplifying Egyptian hieroglyphics into quick, functional letters. As major traders, the Phoenicians helped spread this emerging alphabet around the Mediterranean and beyond, establishing a formal order of letters along the way.

1350 BCE

Homing pigeons 

Use of homing pigeons to deliver mail is believed to have begun with the ancient Egyptians. This method of communication spread to most civilizations.

900 BCE

 

Telecommunication begins: Smoke signals in China

Telecommunication is defined as the transmission of signals over a distance. Soldiers along the Great Wall in ancient China used smoke signals to warn of an invasion. The color of the smoke indicated the size of the incoming force.

8th century BCE

Greeks develop vowels

The Greeks create the first true alphabet by adapting the Phoenician alphabet to map letters to Greek sounds and add vowels.
